Title: Resin-coated steel plate for vessel and vessel employing this
Inventor: SAKAMOTO YOSHIKI
IPC: C25D5/26
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To give an excellent adhesion with a resin layer, and cause no contraction of a resin layer during welding, and also render a corrective coated film unnecessary by coating a non-orientated polyester resin layer on a surface treated steel plate with two layers consisting of the metal chrome layer of a lower layer and chrome hydration oxide layer of a lower layer on the surface of a steel plate. SOLUTION: A non-orientated polyester resin layer is coated on a surface treated steel plate formed with two layers consisting of a metal chrome layer of a lower layer and a chrome hydration oxide layer of an upper layer formed on the surface of a steel plate. A coating method of the resin layer employs a film lamination method in which one made by heat melting material resin pellets to subsequently be made into a film having a thickness of the order of 10-100 μm is press bonded on a surface treated steel plate being heated to a melting point of resin or higher, and an extrusion lamination method in which material resin pellets are heat melted to then be directly extruded for lamination onto the surface treated steel plate from a Ti-die.  Also, in the use of filling a content having strong corrosion behavior, it is available to laminate a film with a primer consisting of a various kinds of resins coated in advance.

Title: Flexible sleeve for fluid pressure device
Inventor: KOTSUKAWA YOSHIHIRO
IPC: F16C9/00
Filed: 1979-06-15
Abstract: PURPOSE: To protect against the production of crack and to improve the durability, by a method wherein a sleeve having two layers of reinforcing reed-screen woven codes between elastic materials is constituted such that there is no overlap at a portion which becomes an outer layer when a sleeve is put to a practical use.  
     CONSTITUTION: A rubber inner layer b, which becomes an outer layer 2 when a flexible sleeve 1 is put to a practical use, is extrusion-molded to form a tube having no overlap and no seam. The tube and a roll (a) are matched together, and reinforcing reed-screen woven codes c and d are wound there-around in the reverse direction to each other. A rubber sheet (e) is further wound around the codes so wound. The resultant work is molded to produce a sleeve 1 in which there is no overlap at a portion becoming an outer layer 2 when the tube is put to a practical use. This prevents from the entry of a mold release agent into an overlapped portion during a manufacturing process, which results in improving the durability. Besides, the sufficient use of the mold release agent permits the improvement of a working efficiency.

Title: Electronic still camera
Inventor: NAGANO MASATOSHI
IPC: H04N5/335
Filed: 1989-03-30
Abstract: PURPOSE:To reduce a release time lag in the range where no re-adjustment is applied by applying re-photometry and re-adjustment of a shutter speed only when an aperture decided at pickup is a value requesting re-adjustment or within a prescribed range on the performance of a camera. CONSTITUTION:A retrial photometry range specific to an interchangeable lens L is set by, e.g. a range in which the accuracy of a diaphragm 2 in the inter changeable lens L is not ensured. When the pickup is started, a motor is driven till a preset aperture is given to an object to stop the aperture. When the aper ture F number exists within the retrial photometry range or is in a prescribed value, after the stop operation of the diaphragm device 2, retrial of photometry and re-adjustment of a predetermined shutter speed are applied. Thus, a release time lag in a range where no re-adjustment is applied is reduced.

Inventor: NAKAJIMA TOSHIO
IPC: H04N9/64
Filed: 1995-03-31
Abstract: PURPOSE: To directly generate cyan, magenta and yellow color signals from a luminance signal and a chroma signal. CONSTITUTION: A color burst is extracted from a chroma signal by a burst gate 53 and fed to an APC 54. The APC 54 synchronizes a phase of a subcarrier fSC outputted from a VCO 55 with a phase of the color burst. An inverting amplifier 52 inverts the phase of the subcarrier fSC and gives the subcarrier fSC after phase inversion to a color demodulator 56. Since the phase of the subcarrier fSC is inverted, the color demodulator 56 generates inverted color difference signals (-(R-Y) signal, a -(G-Y) signal, a -(B-Y) signal). Adders 57-59 adds the inverted luminance signal (-Y) to the color difference signals to generate cyan, magenta and yellow signals.
